I understand. This log is acquired for the purpose of investigating the cause part (server side or application side)
whenperformance is bad.
So I will search whether getting other place of PQtrace() is necessary or not.
And I will reply after the research, please wait for a while a little.

Thank you. I think so, too. Some applications cannot be stopped to add the PQtrace() code.
